How to Embed a JSON Variable Directly
into a DIV Class: A Simple Guide
JavaScript Object Notation (JSON) is widely used in web development for data exchange due to its
lightweight format. When building interactive websites, you may need to embed JSON data directly into
HTML elements such as a div tag. This can be useful when rendering dynamic content without requiring a
page reload.
In this guide, we will walk you through the process of embedding a JSON variable into a div class using
JavaScript.
1. Understanding the Need
Imagine you have some JSON data that needs to be displayed dynamically inside a div element. You want
to avoid reloading the page or refreshing the browser, which can slow down the user experience. By directly
manipulating the DOM (Document Object Model) using JavaScript, you can seamlessly display JSON data in
the required div tag.
2. Preparing the JSON Data
Let's start with an example of a JSON object containing some basic user data:
{ "name": "John Doe", "email": "johndoe@example.com", "age": 29 }
For this example, we will store this JSON data in a JavaScript variable and later display it within a div
element.
3. Creating the HTML Structure
Your HTML structure will contain a div element where you want the JSON data to be displayed. Below is the
basic HTML structure:
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport"
content="width=device-width, initial-scale=1.0"> <title>Embed JSON in DIV</title> </head>
<body> <div id="user-info" class="user-card"></div> <script src="script.js"></script>
</body> </html>
Here, the div element with the ID user-info is where we will display the JSON data.
4. Embedding JSON into the div Class using JavaScript
Now, we will use JavaScript to insert the JSON data directly into the div. Follow these steps:

3.
Create the JSON Variable: In your script.js file (or directly inside a <script> tag), create a
JavaScript object that holds the JSON data.
Access the div Element: Use the document.getElementById() method to access the div by its
ID.
Display the JSON Data: Format the JSON data and insert it into the div using the innerHTML
property.
Here’s a sample JavaScript code to achieve this:
// Step 1: Create JSON variable const userData = { "name": "John Doe", "email":
"johndoe@example.com", "age": 29 }; // Step 2: Access the div element const userDiv =
document.getElementById('user-info'); // Step 3: Embed JSON data into the div class
userDiv.innerHTML = ` <h2>${userData.name}</h2> <p>Email: ${userData.email}</p> <p>Age:
${userData.age}</p> `;
In this example, we use template literals (backticks) to dynamically insert JSON values inside the HTML
content of the div.
5. Style the JSON Data
To make your content visually appealing, you can apply some CSS styles. For example:
.user-card { background-color: #f4f4f4; padding: 20px; border: 1px solid #ddd;
border-radius: 5px; width: 300px; margin: 20px auto; } .user-card h2 { color: #333;
font-size: 1.5em; } .user-card p { color: #555; font-size: 1em; }
This will render a neatly formatted user card on your page.
6. Additional Considerations

JSON Parsing: If your JSON data is coming from an external source, you may need to parse it
using JSON.parse() before embedding it into the DOM.
Error Handling: Ensure to handle cases where the JSON data might be invalid or incomplete, using
JavaScript's try-catch blocks.
Final Output
The browser will dynamically generate HTML content inside the div based on the JSON data:
<div class="user-card"> <h2>John Doe</h2> <p>Email: johndoe@example.com</p> <p>Age: 29</p>
</div>
The Outcome
By following these steps, the user on AskFullStack was able to resolve the
issue. Their custom Blade page started using the correct Filament theme,
ensuring a consistent look and feel across their application.
Conclusion
Embedding JSON data directly into a div class can enhance the interactivity and dynamic nature of your
website. With JavaScript, you can manipulate the DOM to display any JSON object effortlessly. This approach
is particularly useful when working with APIs, user data, or any dynamic content that needs to be updated in
real-time. Keep experimenting with different structures and styles to make the most out of JSON and HTML
integration!
